Thanks Phil for the informative reply. Tesla's website/manual was useless!
I noticed near sunset, the sun hits the charge controller - heating it up when operating, so I put a 5" round motor heatsink bolted to the side of the house with the charge controller *inside* to keep it cool in the afternoon when the sun strikes it. Also put some "elephant snot" aka silicone rubber around the seal/emblem where it may have sucked in some H20 when we had a "gully washer" rain. It's under cover charging station (have 3 charging stations) but it was pretty steamy when it rained in the low 90's. It ran through a complete charge cycle back at 32A (with the sun on it at 92F), yeah! Trying the simple solution first - before hacking it apart and re-doing the enclosure with a muffin fan. I also put dielectric grease on the connector at the unit - and on the car connectors. While I was at it, did the Bolt and Leaf J1772 connectors as well. Have a renewable energy day, Mark Mark E.

If this serial digital signal doesn't reach the EVSE for whatever reason, it will limit amperage. One way to test is to try another adaptor. The Gen1 used an all-analog system with a thermistor and a fixed resistor to tell the EVSE about the difference. Gen1 topped out at 40A, whereas Gen2 is only 32A max.
